<p>In a metal-clad, gas-filled, multiphase high-voltage switch gear, having a partition (12) between the busbar chamber (21) and the switch chamber (14), the connection between the two chambers (14, 21) takes place via ducts (13) inserted diagonally in the partition (12), which ducts (13) are arranged in the one direction in the spacing of the busbars (1) and, in the other direction, in the spacing of the poles (6) of the circuit breaker or load isolator (9). As a result, straight-line, crossing-free connections are possible in the busbar chamber (21), between each busbar (1) and the associated duct (13), via the respective isolating or three-position switch (8), while the connecting lines (15a, b, c) in the switch chamber (14) run to the poles (6) in mutually parallel planes, once again without crossing. …<??>Apart from minimising the switch gear dimensions and increasing the electrical strength as a result of the diagonal arrangement in the busbar chamber (21), in conjunction with a square housing (20), the installation of earthed separating walls (22, 32) between the phases in the two chambers (14, 21) allows effective reinforcement of the outer walls (17) and, above all, the partition (12) to be achieved. Likewise, in the event of a fault, phase shorts with high current arcs are prevented. The stated advantages can also be used in the case of separated multiple busbar systems. …<IMAGE>… </p> |
